Abstract

Etilene viene omopolimerizzata, o copolimerizzata con un'alfa-olefina, in presenza di una composizione catalitica formata da :( i ) un componente solido di catalizzatore (procatalizzatore), contenente titanio, vanadio e cloro, secondo le seguenti proporzioni molari:Ti (1); V (0,3-3); Cl (4-12);( ii ) un cocatalizzatore alluminio trialchile o cloruro di alluminio alchile; e ( iii ) un attivatore scelto in particolari classi di cloroderivati organici.
